(a) Definition of the substrate rotation angle ω. Background-subtracted TWAXS images from LB monolayers of C14F, measured at (b) = 0 (normal incidence) and (c) = 9°. (d) Expected φ-dependence of qz along the `Bragg ring' at qxy = 1.25 Å−1, via equation (15), for = 0 (black) and 9° (red). (e) Background-subtracted peak intensity for the data at = 9° in (c) as a function of φ. |
